After got introduced to the palm oil production potential in Tanzania by Anna Segerstedt from the Institut for Environetal Economics and World Trade at the Leibnitz University Hannover with respect to sustainability standards the point was clear: there is no chance under the assumed conditions to produce palm oil for the export market as well as for label production due to export barriers and costs linked to certification respectively. Ms Segerstedt found however, that according to her results the palm oil production for the local market is competitive. Zora Lea Urech from the Department of Environmental Sciences at ETH Zurich outlined in her interesting presentation possible drivers leading to further deforestation in the eastern part of Madagascar taking into consideration the main components of the livelihood strategies of small farm-households. The complex land tenure system, next to other factors, hinders a sustainable use of the forest ecosystems and need to be further investigated.

This is a sample of some of the great mixed cropping, agroforestry and biofuels oral presentations at Tropentag Strategies to Use Biofuel Value Chain Potential in Sub-saharan Africa to Respond to Global Change Enhancing Low-productivity Farming in Tanzania and Linking to SMEs – Stefan Sieber Some of the most significant global drivers stem from energy demands. This study examined new strategies to improve value chains and biofuel potential in order to provide communities in Sub-Saharan Africa with multiple energy services. The study took place in Tanzania, however global applications of the findings was one of the overall objectives. One way to improve energy demands in developing countries is though linking small scale farmers with small- to medium-scale enterprises. This research project worked with stakeholders in order to develop feasible strategies to maximize profit. The output from this collaborative effort was the development of global scenarios (applications in other countries), biomass production, consumption patterns, as well as a participatory biomass value chain. The objective of the research was to conduct a sustainability impact analysis and an information system for policy/decision support.
